**Absolute value**

The absolute value means the distance of a number from zero. So, absolute value is always positive.

The absolute value of 2 would be denoted by |2| and its value would be 2, since the distance from zero is 2. Also, the absolute value of the number -2 is also 2, since the distance of the number -2 from zero is 2.

The absolute value of *a* is the number *a* itself, if the number* a* is positive. If the number *a* is negative, the absolute value of *a* is the opposite number of *a*.

This is the definition of absolute value, and it is expressed in the form of the formula below

The absolute values of some numbers

**|4|=4 |-4|=4 |-ℼ |=ℼ |-234|=234**

Expression |3 - 5| means the distance between the numbers 3 and 5, which is 2. That is |3 - 5| = | -2 | = 2

The distance between numbers 2 and -6 can be found by the absolute value. |2 - (- 6)| = |2 + 6| = | 8 | = 8
